Turn Signal Light and Hazard Warning Light
General Description
The circuit consists of a turn signal switch
(combination switch), turn signal light, hazard
warning switch and flasher unit. When the turn
signal light switch is turned on with starter switch
on, turn signal light will operate. When turn signal
light is flashing, indicator light in meter also starts
flashing. When hazard warning switch is turned on,
current flows to flasher unit through hazard warning
switch to cause hazard warning light to flash
independent of position of starter switch. At the
same time, indicator lights in meter also start
flashing.
